Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. There are 4 types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter.
Flu symptoms can include any or all of the following:
- Body aches
- Runny nose and congestion
Why do people usually get the Flu in winter?
Researchers have pinpointed the key reason why people are more likely to get sick from flu during winter months:
- The virus lives longer indoors in winter, because the air is less humid than outside
- We spend more time indoors which makes it easier for the virus to spread
Want to avoid getting the flu?
- Wash your hands often to remove germs and keep them clean
- Increase water vapor in the air with humidifiers at home, school, work, and even hospital environments
